Dissolved long-lived radium isotopes for submarine groundwater samples collected from November 2022 and March 2024 along the West Florida Shelf

Specific activities of long-lived dissolved radium (Ra-226, Ra-228), collected from U.S. Geological Survey small boat operations in the West Florida Shelf from November 2022 to March 2024. Small boat samples include surface water, bottom water, and submarine groundwaters from three well transects along Nature Coast, Indian Rocks Beach, and Venice Headlands. This project investigates how boundary sources, including rivers and submarine groundwater discharge, deliver important nutrients and metals to the coastal ecosystems of the West Florida Shelf. Here, dissolved radium isotopes have been measured to trace boundary sources of nutrients and metals entering the West Florida Shelf.
